there are 2 extensions on http://kmeleon.swiftfree.net one is a simple macro that uses css to remove all colours and images from a page it's called printify. the other uses a webservice to manipulate the page according to your needs..can remove a certain elemement etc it's called print controller..also check nukeimage by joykillr which enables removing a specific image from a page by right-clicking on it.

If the options in print preview are currently not the best then it would be a nice feature request to improve them also by default!
[But up to such an program improvement I will also test the suggestions (the 2 extensions) of disrupted!]
